One thing Hong Kong is not is boring. There's so much to do here that making the choice of tour or activity is sometimes a difficult thing to do. Exploring the city on an organised tour is really the best and most efficient way to aquaint yourself with the many faces of Hong Kong and the difference between an after-dark tour and a day one is immense.
Either way, you're going to have a lot of fun getting to know the magic that is Hong Kong. Forget language barriers and other hassles and put yourself into safe hands.
